512k Hyperdrive SSD hack... suggestions? Need to run power.

Upgraded to the latest firmware, and I get a whole different type of errors.  Now, it'll boot after a fresh format & install on the first try only.  The second try results in a Sad Mac, and the third try onward are question mark floppies.

It's really weird.

Hmm, maybe it's a manifestation of the problem techknight was describing?

Try partitioning and formatting the SD card on a modern Mac in HFS Extended, and then go over to an older Mac and reformat (but not repartition) it in HFS Standard using Finder's format command.

I don't have the slightest clue if it would work (and probably won't because it needs drivers), but it's worth a try?

Also try to align the partition on the 1024 boundary manually. That might work.

Another thing is that the Plus (and presumably any SCSI upgraded 512k as well) needed an interleave of like 2:1 or 3:1, or something like that.

This is weird!

Michael McMasters got back to me.  He doesn't know anyone who's used it with a 512k or a Plus.  Unfortunately it was my last one and I already stuck it into and SE/30 that's going to be shipped out.

In any event, when I get another one, he said I can hook it up via USB and while it's connected to the 512k simultaneously, then run a utility to capture the data in real time and save it to a log.

I'll send him the log and he's going to analyze it, see what's going on.
